      Enhanced Psilocybin Production     

I xeroxed this a year or two ago, couldn't find it again for a while and I just found it in a stack of papers under a folder that I keep references about psilocybin in.  Its from Chem. Abs (vol. 111, 1989).  I recommend looking at the German patent, too.



111:132556f Synthetic nutrient medium for fungal manufacture of indole alkaloids.  Gartz, Jochen (Akademie der Wissenschaften der DDR) Ger. (East) DD 255,749 (cl. C12P15/00), 13 Apr 1988, Appl. 295,994 06 Nov 1986: 3 pp.  A synthetic nutrient medium which enhances yields of indole alkaloids such as psilocybin and psilocin with fungal cultures is described.  Psilocybe cubensis was cultured on 1 L medium contg. glucose 80, NH4 succinate 1, glycine 9, KH2PO4 0.1 g, yeast ext. 50, thiamine.HCL 3 mg, agar 0.2 g, MgSO4 71, ZnSO4 0.5, MnSO4 0.8, CuSO4 0.8, Na molybdate 0.25, and FeSO4 5 mg for 50 days at 18-26.  The pH was adjusted to pH 3.5 before the fermn.  After sepn. and drying of the mycelium, the psilocybin and psilocin content of the mycelium was 1.10 and 0.2% resp.  A comparable culture on 6% malt ext. soln. produced 22 g mycelium contg. 0.15% psilocybin and no psilocin.

      Re: Enhanced Psilocybin Production     

How effective is the mycelium growth in nutrient broth method for the growth of Psilocybe cubenis?  Does this species do well for growth in a submerged environment, or would it need O2 percolated to ensure proper respiration.  I ask because i've seen very few reports of people attempting this method, when from a maintenance point of view it sounds far simpler then actually growing the fungus into the fruiting stage on a solid media.  Furthermore it would extremely easy to propagate, simply removing some of the mycelial mass and placing it into a new growth container.  The resulting biomass could be filtered, dried, crushed into a powder and weighed out into capsules.  Or, the alkaloids could be extracted into a solvent and deposited on a consumable media, dried and frozen for safe keeping.  With minimal costs potentially hundred or possibly thousands of grams could be produced in a few weeks to months.  Hey... this sounds good! Dammit I could pay for my tuition pretty easy AND have the summers off...cool

      Re: Enhanced Psilocybin Production     

"growth in a submerged environment" is a bad idea --- from what I recall, it does not produce appreciable amounts of psilocin, psilocybin. Submerged cell culture as such is no good. Seems to need surfaces & structures (at least to the level of mycelia) prior to alkaloid production. Porous materials, such as the common growth media, are ideal because they provide both surfaces and air exposure, encouraging "macro" structure formation, mycelia. Further development to the fruiting bodies is uneccessary before harvest. But you won't get any psilocybin to speak of from submerged cell culture.

      Re: Enhanced Psilocybin Production     

Thiamine (C12H17ClN4OS) promotes glucose utilization thereby increasing indole alkaloids. The idea is that the more sugar consumed the higher the cell activity, growth, and alkaloid yield. Omission of thiamine only reduces alkaloid yield partially.

In general all aspects of this solution contribute to the production of psilocybin, glucose being one of the most important. Omission of glucose yields undetectable alkaloid content.

Boron is a micronutrient that helps regulate sugar flow and is a component of cell wall structure. It seems to me that it is a missing component of typical nutrient solutions; unless it is present in the organic agar. (?)

A similar solution, in the following reference, @ 85 F, under filtered aeration or aggressive agitation for 7 days, potentially yields 3750 mg dry material containing 38.25 mg of pure psilocybin (no psilocin) per L.

Gartz's 262.6 mg in a single batch is impressive, but 267.75 mg could be produced using consecutive 7 day batches in the same amount of time.

Cobalamin (C63H90CoN14O14P) is associated with blood cell formation in animals, as well as maintaining the health of nerves in primates. Cobalamin is typically not used by or found in plants, for this reason it can be noted that vegetarians are recommended to supplement B12 in their diet.

"It's paradoxical that the bacteria that live in our guts make more vitamin B12 than we need, but it's not available to us since it cannot be absorbed from the large bowel. There is so much vitamin B12 in feces that the presence of this vitamin in lakes and rivers is used as a measure of fecal contamination."

-Bernard Aaron Cooper, MD, C.M. Clinical Professor of Medicine (Hematology), Stanford University

We can conclude that organic fertilizer compost substrates would have a relative high B12 content. Mean while organic plant substrates would have undetectable amounts. At this level both have similar yields but due to organic complexity is difficult to isolate the effects of B12. I believe from the comparison of key nutrient needs in this fungus and typical plant nutrients that it is well adapted, although not limited to, the break down of organic plant matter that does not contain B12.

The guidelines for nutrient solutions are that they contain nutrients in amounts that are proportional to the tissue composition and in a total solution concentration that does not damage the tissue.

Many funguses grow rapidly in an acidic environment (3 - 5 pH). Ours displays higher yields of alkaloids and biomass between 4 - 4.6 pH but loses durability and suffers from tissue damage and possible cellular ruption due to solution agitation during the process of aeration. I'm sure we could build our way around that though. cool

      Re: Enhanced Psilocybin Production     

    Typical Ps.C. cultures grown by various organic substrates achieve .4 - .6 alkaloid yields. Typical nutrient enhanced substrates achieve slightly higher yields of alkaloids. Liquid cultures can effectively achieve 1 - 1.1 alkaloid yields by making essential nutrients and carbohydrates easily available.

    This is the general potency of this strain; attempts to further improve nutrient uptake will most likely only result in a higher biomass yield. In the instance of the introduction of tryptamine to yield 3% psilocin alkaloid, I view it as a novel biosynthesis mechanism, operating externally of the natural model of the organism.

    Total biomass, although affected accumulatively, is proportional to carbohydrate uptake. I have heard unofficial reports of rapid growth with dextrose as well as organic honey, which is composed of multiple complex sugars. Perhaps a more efficient mixture of carbohydrates then just glucose could be developed.

    I assume that the growth acceleration that occurs at a lower pH is because nutrients are able to permeate the cellular equilibrium easier. Taking advantage of this requires a device capable of aerating the solution without disturbing the mycelium.

    This method of harvest is far superior to fruited bodies in relation to alkaloid yields, processing, extraction, and overall time.

      Re: Enhanced Psilocybin Production     

    If boiling 75 L of methanol isn't your idea of time saving, cost efficient or fun, you can opt to process your ground-dried biomass in 75 (10 g / 1 L) batches. The major benefit being that you can reclaim most your solvent, eliminating the need to buy bulk methanol. The downside is the time involved, even under vacuum this is going to take a little while. Under optimum conditions we could still complete the entire process in less than two weeks.

    Perhaps a reflux percolator could be implemented to percolate the bulk material with 1 L methanol while collecting extracts in the distillation chamber. (i.e. the methanol condenses from the distillation chamber into a reservoir layered with: ground biomass and perculate, inert filtrate medium, and filter material; then drains back into the distillation chamber.) Percolation should be complete within 4-24 hours. Fastest results would be seen if condenser displaced about 20C. Alternatively the reservoir could act as a condenser with the addition of a cooling coil to displace vapor temperature and instigate methanol condensation while passing thru the biomass perculate. Biomass should be free of alkaloids upon completion and can be tested for their presence using Keller's reagent. Remaining methanol is distilled off.

Under optimum conditions the entire process could take less than a week and a half.shocked

Slight correction:

It should be notated that the above methods yields are actually obtained with 2000 g of glucose to yield a 1.02 percent alkaloid content by day 7, unfortunately this carries a side effect whereby the alkaloid content diminishes to 0.15 by day 11. A solution with 1000 g of glucose would yield only 0.52 alkaloid content but continues to full growth at day nine with no diminishing of potency.

I think the methanol volume could bee reduced way down and still extract about as much product. 

The ideal would bee a huge vacuum soxhlet, so you could boil methanol at very low temps and extract it that way.  The process would bee nice and automated and you could easily recycle the methanol.

Methanol adds flavor. blush *j/k*

Actually the large volumes of methanol are to allow for a single complete extraction of solubles from the bulk biomass with a 10G:1L ratio. In a production line environment right after a majority of the methanol is distilled the reclaimed solvent could be used to start seeping another batch. 

In a situation where methanol is readily available this is the simplest solution and fully adheres to the K.I.S.S. principal. But it could also add certain volatility and incarcerating smells to the process.

In a previous post I mentioned a "reflux percolator" for lack of better words.frown (Basically a Soxhlet) An apparatus that refluxes the biomass with condensing methanol vapors and collects resulting extracts in the distillation chamber. I believe it would still need to distill the same volume of solvent in order to complete the extraction so it would take roughly the same amount of time but only require 1 L or less of solvent. Still being considered high levels of methanol?  

The uptake of solubles is rapid (1 hour; 10:1) while agitated at 40-45 C, and without significant product degradation. The same process can take up to 12 hours at rest and normal room temperature.

The 65 C during solvent distillations is a little rough on the products integrity, but I didn't have a 55-gallon drum vacuum adapter handy.

Thanks for the suggestion / solution. A vacuum soxhlet is definitely the ideal embodiment of this apparatus.

If we have to extract 20-40 g of solubes from 750 g of biomass, any ideas on desired soxhlet solvent volume?

Ref: Catalfomo, P. and V.E. Tyler, Jr. "The Production of psilocybin in submerged culture of Psilocybe cubensis" LLoydia 27:53-63, 1964

Pellets of Psilocybe cubensis produced in medium no. 1 [ammonium succinate (1 g), Glycine (9 g), Glucose (5 g), yeast extract (.5 g), KH2PO4 (.1 g), thiamine hydrochloride (.003 g), (NH4)6Mo7O24-4H2O (.05 mg), ZnSO4-7H2O (.3 mg), MnCl2-4H2O (.35 mg), FeSO4-7H2O (2.5 mg), CuSO4-5H2O (0.5 mg), MgSO4-7H2O (0.5 g), distilled water, to make (1.0 L), adjust to pH 5.5 with hydrochloric acid] accumulated psilocybin but not psilocin. Maximum production of the former compound occurred on the seventh day (0.52 per cent, dry weight of mycelium), whereas growth attained its maximum (average 112.6 mg, dry weight of mycelium per 30 mL of medium in a 125 mL flask) on the ninth day.

Maximum yields of both psilocybin and mycelium occurred in the acid pH range (4.0-4.6). However, the acidid nature of the mycelium does not preclude the possibility that thte internal pH of the organism is maintained at a different level by an efficient buffering system. Failure to find psilocybin in the medium may be attributed to its instability in the vigorously agitated acid medium, although permability factors are probably also involved.

In the absence of a readily assimilable carbon source (glucose), detectable amounts of psilocybin did not accumulate. Omission of ammonium succinate did not significantly alter the pH of the medium but it did lower psilocybin yields. Without yeast extract, mycelial production was retarded at five days, and culture liquors remained acidic through the eleventh day. Adaption and/or synthesis of necessary precursors nevertheless permitted a continued increase in growth which was accompanied by a rapid increase inthe yield of psilocybin by the seventh day. Similar results were obtained for media from which both yeast extract and thiamine had been omitted, except psilocybin levels remained lower.

According to Cochrane (5) most fungi have an absolute requirement for thiamine; however, where low levels are needed, synthesis takes place after initiation of growth. Under conditions of thiamine deficiency, glucose utilization is impaired, which may account for initial inhibition of growth when yeast extract or that ingredient and thiamine were omitted from the medium. Although glycine constituted more than one-half of the total weight of the dissolved solids in medium no. 1, the organism grew and metabolized efficiently in its absence.

The influence of different concentrations of glucose, ammonium succinate, and potassium acid phosphate in medium no. 1 was noted. A low level of glucose was associated with a rapid rise in exracellular pH, and lower levels of product accumulated. Doubling the normal amount of carbohydrate promoted psilocybin accumulation which reached a level of 1.02 percent (dry weight) by the seventh day. After eleven days, this level dropped to 0.15 percent; a similar sudden decline in psilocybin content was also noted in those flasks containing a reduced phosphate concentration. The significance of the low pH levels after eleven days is unknown. In contrast, levels of ammonium succinate which were one-half or twice that of the normal medium had no significant effect upon pH or psilocybin production.

Extracellular tryptophan added to replacement flasks did not enhance psilocybin production, but, instead, underwent degradative reactions of the type reported to occur in Neurospora and other fungi (5). This conclusion is based on the observation that a progressive increase in kynurenine, a catabolic product of tryptophan metabolism, paralleled the disappearance of tryptophan. These results are not necessarily contradictory to those obtained by Brack, et al. (2) since they used a different organism and different experimental design which preclude a direct comparison. However, our results do establish the existance of a direct relationship between psilocybin production and mycelial growth. Utilization of th replacement culture technique served to separate growth and psilocybin production, whereas the method of Brack, et al., did not afford this distinction. It was concluded that psilocybin production is so intimately related to mycelial proliferation that the nutrient-deficient replacement medium was of little value inthe study of psilocybin biosynthesis. However, the technique had previously proven satisfactory for biosynthetic studies of other indole derivatives in fungi (3).

Increasing the scale of fermentation from 30 mL of medium in 125-mL flasks to 300 mL in 2800-mL flasks markedly affected psilocybin production. Significatn differences in yields did not appear until after the seventh day when accumulation of product ceased, and a more rapid decline occurred in the large flasks as the pellets became physiologically older. Although the cause of this phenomenon was not established, it way be attributed, at least in part, to differences in the efficiency of aeration of the cultures.

As foxy2 clearly pointed out, there are many points for refinement; it's definitely a work in progress.

    Over at the Shroomery there's been mention of starting off with a more potent species then adjusting the solution to meet it's needs by testing biomass yields in an array of cultures with different nutrient makeups. Higher biomass would be direct result of better glucose utilization and would most likely have higher alkaloid content. If these species can be efficiently culture in a liquid nutrient solution and present increased activity in the presence of raised glucose concentrations, the theoretical alkaloid yields could easily reach over 2% psilocybin.

    I believe that would be the highest psilocybin content that I've ever seen reported. Roughly 4 times stronger then you're average Ps. C. culture. High volume mass production techniques could yield over 15 g of psilocybin... but it's only theory for now.
